Abstract
COVID-19 is threatening the whole world. This paper aims to explore the correlation between climatic factors and the morbidity of COVID-19 in Wuhan, China, mainly by using a geographic detector and GWR model. It was found that the response of the morbidity of COVID-19 to meteorological factors in Wuhan is different at different stages. On the whole, the morbidity of COVID-19 has a strong spatial aggregation, mainly concentrated in the central area of Wuhan City. There is a positive correlation between wind speed and the spread of COVID-19, while temperature has a negative correlation. There is a positive correlation between air pressure and the number of COVID-19 cases. Rainfall is not significantly correlated with the spread of COVID-19. It is concluded that wind speed, relative humidity, temperature, and air pressure are important meteorological factors affecting the spread of COVID-19 in Wuhan. Any two variables have greater interaction with the spatial distribution of the incidence rate of COVID-19 than any one factor alone. Those findings not only provide a new insight for the key intervention measures and the optimal allocation of health care resources accordingly but also lay a theoretical foundation for disease prevention, disease intervention and health services.
Highlights
A pneumonia outbreak of unknown cause, detected in Wuhan, China, was first reported to the World Health Organization (WHO) Country Office in China on 31 December2019
Based on the GWR4 software, the incidence rate is taken as the dependent variable and those six climatic factors, including temperature, relative humidity, rainfall, wind speed, and air pressure, are taken as explanatory variables
It is clear that temperature and wind speed are the most important controlling factors of spatial differentiation of the incidence rate of COVID-19
Summary
A pneumonia outbreak of unknown cause, detected in Wuhan, China, was first reported to the World Health Organization (WHO) Country Office in China on 31 December. By 2 January 2020, 41 admitted patients with confirmed infections by this virus, named Corona Virus Disease 2019 (COVID-19), had been identified in hospitals in. At 10:00 on 23 January 2020, Wuhan New Coronavirus Epidemic Prevention and Control Headquarters announced that the city bus, subway, ferry and long-distance passenger transport were suspended. The airport and train stations were temporarily closed. Case numbers in China stabilized at around
